About Frost and Seed

Frost and Seed is run by Paul Gunder, the founder of Rocky Mountain Apps. The site answers the timing questions gardeners search for most: when the last spring frost is behind you, how late a fall crop can still go in, how long seedlings stay indoors, and how far apart to plant.

How a page gets made

Every page starts with a source. Before a figure goes on the site, we save a copy of the NOAA data file or university Extension publication it comes from, with the web address and the date we fetched it, and quote it in our notes. The figures then live in a typed data file, not in the text of the page. The words on the page pull each number from that file, so a number cannot be typed in by hand or drift away from its source.

When two Extension sources give different answers, the page shows both and names them. When a source is old or its publisher is unclear, the page says so. Page text is our own wording. We quote short phrases with attribution. We reproduce a table only when it comes from a public university Extension publication or from NOAA, and we credit and link each one on the page that uses it. We never copy tables from commercial garden sites, and we do not reproduce diagnostic keys or photographs.

What this site is not

It is not a calculator site. Calcimator, a sister project, has the garden calculators, and we link to it rather than rebuilding them. It is not affiliated with any university, with the USDA or NOAA, or with any seed or garden supply company, and it carries no affiliate links today.

Reporting a mistake

If a figure is wrong or a link is dead, tell us on the contact page and name the page. Corrections are logged on the changes page.
